This paper investigates arbitrage chains involving four currencies and four foreign exchange trader-arbitrageurs. In contrast with the three-currency case, we find that arbitrage operations when four currencies are present may appear periodic in nature, and not involve smooth convergence to a "balanced" ensemble of exchange rates in which the law of one price holds. The goal of this article is to understand some interesting features of sequences of arbitrage operations, features which might… 

Fact and fictions in FX arbitrage processes

The efficient markets hypothesis implies that arbitrage opportunities in markets such as those for foreign exchange (FX) would be, at most, short-lived. The present paper surveys the fragmented

Double exponential instability of triangular arbitrage systems

If financial markets displayed the informational efficiency postulated in the efficient markets hypothesis (EMH), arbitrage operations would be self-extinguishing. The present paper considers


In the Leijonhufvud synthesis, economies are self-adjusting within some 'corridor', but not outside. In a previous paper, Cross et. al. (2010), used combinatorial analysis to see if arbitrage

A mesoscopic stock market model with hysteretic agents

Following the approach of [22], we derive a system of Fokker-Planck equations to model a stock-market in which hysteretic agents can take long and short positions. We show numerically that the

In memory of Alexei Pokrovskii: his hysteresis effect on economics

This memorial note assesses the impact of Alexei Pokrovskii, a pioneer in the mathematical analysis of systems with hysteresis, on economic analysis. Apart from the seminal contributions made, Alexei


This paper attempts to estimate the impact of population ageing on house prices. There is considerable debate about whether population ageing puts downwards or upwards pressure on house prices. The

Consensus in Asynchronous Multiagent Systems. II. Method of Joint Spectral Radius

These methods are based on the idea of using the notion of joint/generalized spectral radius of matrix sets to analyze the rate of convergence of matrix products with factors from the sets of matrices with special properties.

Dynamic Model of Optimal Production Control in a Hysteretic Behaviour of Economic Agents

The hysteresis nature of demand, depending on the price ratio and purchasing power, is well-known, but mathematical models that describe this relationship have not been developed so far. This article



One-Way Arbitrage and Its Implications for the Foreign Exchange Markets

The relationship between spot and forward exchange rates and domestic and foreign interest rates is examined with transactions costs in all markets. Market participants choose the least-cost method

The Limits of Arbitrage

In traditional models, arbitrage in a given security is performed by a large number of diversified investors taking small positions against its mispricing. In reality, however, arbitrage is conducted

Arbitrage Networks

This paper studies the general equilibrium implications of arbitrage trades in segmented financial markets. Arbitrageurs choose a category of trades to specialize in. This results in an equilibrium

Anomalies: The Law of One Price in Financial Markets

The Law of One price states that identical goods (or securities) should sell for identical prices. In financial markets the law of one price is thought to hold almost exactly, and is the basis for

Order Flow and Exchange Rate Dynamics

This paper presents an exchange rate model of a new kind. Instead of relying exclusively on macroeconomic determinants, the model includes a determinant from the field of microstructure finance—order

The Law of One Price Over 700 Years

This paper examines annual commodity price data from England and Holland over a span of seven centuries. Our data incorporates transaction prices on seven commodities: barley, butter, cheese, oats,

The Law of One Price - a Case Study

We use retail transaction prices for a multinational retailer to examine the extent and permanence of violations of the law of one price (LOOP). For identical products, we find typical deviations of

The Microstructure Approach to Exchange Rates

Historically, the fields of exchange-rate economics and microstructure finance have progressed independently of each other. Recent interaction, however, has given rise to a microstructure approach to

A Century of Purchasing-Power Parity

This paper investigates purchasing-power parity (PPP) since the late nineteenth century. I collected data for a group of twenty countries over 100 years, a larger historical panel of annual data than
